Bending-Loss-Resistant Distributed Temperature and Strain Discriminative Brillouin Sensor Based on 98 mol% Germania-Doped Few-Mode Fiber

Temperature-strain cross-sensitivity and bending-induced optical loss are two major limitations that challenge the in-situ application of distributed optical fiber sensors. Researchers have attempted to solve these two issues but seldom can overcome both. This paper proposes a novel bending-loss-res...
